software, including guidance on which calibration options and
models suit different purposes. Other topics covered are the
different types of models, mapping multiple subjective datasets
onto a single scale, objective video quality model validation, and
Digital Video Library.

This video demonstrates how the eyes and
ears work together to understand speech. This is called
audiovisual perception or cross-modal perception. Audio of
a woman saying "ba ba ba" has been dubbed over the

Tutorials from the 1990's
This 1996 tutorial is an overview into early parameters
developped by NTIA. Many of the features and parameters in today's
VQM software are
updated and improved versions of these older algorithms.
This tutorial from the late '90s explains why video quality
metrics are needed.
